Abstract

The scope of this study is to design a noninvasive method to characterize skin aging using biophisics objective parameters in healthy sardinian peoples of fifth age. In order to evaluate their sensibility and specificity the following parameters were studied: surface roughness parameters used in metallurgical industry, pH and sebum quantification in skin’s hydrolipidic film, water quantification at the stratum corneum level, quantification of melanin in epidermis and haemoglobin in dermal vessels.
Our results confirm significant differences of the skin between first and fifth age. Our results, finally, show that the most specific parameter in teh assessment of aged skin seem to be anisotropy of the furrows.
